my guess is that this commit is the problem:

        http://mail-index.netbsd.org/source-changes/2007/05/29/msg186117.html

it changed the size of struct ifreq, pushing the ifru_flags flags further
into memory by sizeof(struct sockaddr_storage).

christos?  the comment says it should be backwrds compatible.
